On November 12 2025, IBM announced a major leap in its quantum computing roadmap. The company revealed the IBM Quantum Nighthawk processor — engineered to achieve quantum advantage by late 2026 and fault-tolerance around 2029.
These developments close the gap between experimental setups and practical, problem-solving quantum systems.
Key highlights:
-
The Nighthawk chip will ship to users by the end of 2025, with scalability targets of 7,500 two-qubit gates in 2026 and 10,000 by 2027.
-
IBM emphasizes a full-stack approach: hardware + software + error correction to enable real-world applications.
-
Analysts point out that this milestone moves quantum computing from “lab curiosity” to “business tool.”
Why it matters for PostQuantum Apps:
As quantum hardware becomes practical, classical cryptography faces increasing risk. This reinforces the urgency of migrating to quantum-resistant encryption such as ML-KEM and CRYSTALS-Dilithium — exactly what PQApps delivers.
“Those who prepare now will lead tomorrow.”
